No one was struck and there were no injuries. Const. Andy Pattenden said two of the Pokemon players were 19 years old.

Police said officers arrested a woman at an apartment in the building and seized a pellet gun.

York police said they’ve received several calls from concerned citizens about groups of people walking around in the region, but that most of them were just playing the popular smartphone game.

Pattenden said the downtown location of Saturday night’s incident is a “meeting place” for the game and as a result has seen the number of people hanging around increase significantly since the app’s release earlier this month.

Police are reminding players to be aware of their surroundings while hunting the virtual creatures and to not run afoul of trespassing laws.

Pattenden said there have so far been no injuries of people playing the game in York region nor have police been called to remove players who wandered onto private property.
